A Chinese Startup May Have Cracked Solid-State Batteries (engadget.com)

hackingbear writes: According to Chinese media, Qing Tao Energy Development Co, a startup out of the technical Tsinghua University, has deployed a solid-state battery production line in Kunshan, East China. Reports claim the line has a capacity of 100MWh per year -- which is planned to increase to 700MWh by 2020 -- and that the company has achieved an energy density of more than 400Wh/kg, compared to new generation lithium-ion batteries that boast a capacity of around 250-300Wh/kg. Details beyond this are sparse. The headline news here, if accurate, would be that the company has managed to put solid-state batteries into high volume production, but it's not clear how Qing Tao Energy Development has achieved this, nor what price points are involved. Furthermore, while a capacity of 100MWh is not to be sneezed at, it still only equates to fewer than 2,000 long-range EVs per year. Nonetheless, the news demonstrates that progress is happening in the solid-state battery arena. We might not feasibly yet be at high volume production, but we're on our way.

    The article notes that information is sparse. Hopefully more will be released soon. The production rates and energy density are both significant. Cost, including the environmental manufacturing and disposal costs, the number of recharges, and safety requirements are all necessary considerations in bringing a battery to market.
